SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 711,977, dated October 28, 1902.

Application filed February l, 1902. Serial No. 92,199. (No model To aZZ- whom, it may concern,.-

Be it known that I, JULIUS KALMR, asubject of the Emperor of Austria-Hungary, and a resident of Raab, Austria-Hungary, have invented certain new and useful Improvements in Sad-Irons, of which the followingis a specication.

My invention relates to sad-irons adapted Ato be heated by alcohol or other suitable combustibles, and has for its object to provide such irons with a regulating-valve and with devices for eiectively cooling the alcohol or other liquid combustible in its reservoir.

In the annexed drawings a sad-iron constructed according to my invention is shown, in Which- Figure l is a longitudinal vertical section of the iron. Fig. 2 shows in similar section a modification of detail. Figs. 3 and show in longitudinal and cross section another modification. Fig. 5 shows in plan view a part otl a modified form of the burner.

The sad-iron is composed of two parts, the upper part 1 and the lower part 2. These two parts are attached to each other, with a space between them, by screw-bolts 3, which are inserted through enlarged holes and nonheat-conducting washers in such manner as to be non-heat conducting. The upper part 1 is provided with the handle 4, between the branches 5 of which is disposed the reservoir 6 for containing the alcohol or similar combustible. Into an opening in the bottom of the reservoir 6 is inserted a tube 7, which is open at the bottom and top, extends above the normal level of the liquid in the reservoir, and incloses the spirit-conducting tube S,the space between the two tubes being tilled with a packing 9 of asbestos or similar material. The spirit-conducting tube 8 enters the hollow space in the top part 1 of the sad-iron, there forms a loop or bend, leaves the top part 1 at 10, and enters the hollow bottom part 2 at 11 and is connected to the burner-tube 12. The vertical part of the burner-tube 12 passes upward through the top part 1 and contains a valve 13, the seat of which issituated between the connection of the spirit-conductin g tube 8 with the burner-tube 12 and that horizontal part of the burner-tube containing the iiam e-apertures. The valve 13 is screw-thread ed and may be adjusted by a button 14 for controlling the flame. The gasification of the spirit takes place in that part of the conducting-tube 8 which is situated in the bottom part 2. To prevent the vertical part of the burner-tube l2 from heating the top part 1 of the iron by conduction, the apertures in this latter part through which the tube l2 passes are somewhat larger than the diameter of this tube, so as to avoid metallic contact of the two paris, orasuitable insulation ot' any other kind may be employed.

The top part l of the sad-iron is at opposite ends provided with suitable apertures 15 to create a current of air through the hollow part l for the purpose of cooling the conducting-tube 8 and of keeping cool the reservoir 6. The bottom part 2 of the sad-iron is provided with an opening 16 forV permitting the igniting of the Hame. I

In the modification shown in Fig. 2 the cover 17 of the reservoir is provided with lateral strips 18, which rest upon and are secured to the branches 5 of the handle, and the cover is removably secured to the handle branches by means ot screws 25. In this case the conducting-tube 8 is made to enter the reservoir through the cover, as shown.

In the modification shown in Figs. 3 and 4 the hollow bottom part 2 of the sad-iron contains a ilame-deiiecting shield 19,which, starting above an aperture 2O in one side of the part 2, partially surrounds the conductingtube S, passes toward the bottom of the iron parallel to its side, covers the burner-tube 12, and runs upward again along the opposite side of theiron, where itends above another aperture 20. Below the burner-tube 12 and parallel to the same are placed two perforated air-supply tubes 21, which are bent upward near the end of the part 2 and pass through the cover of this latter, opening into the space between the top part 1 and bottom part 2.

To increase the eect of the burner-tube 12, it may be provided with branches 22, as shown in Fig. 5 of the drawings.

The device operates as follows: In the sadiron constructed according to Figs. l and 2 the spirit or other liquid combustible is conducted by a wick 23, which .ills the entire length of the tube 8, part of this tube being situated in the bottom part2 of the iron above the burner-tube 12. The valve 13 is now IOO opened sufficiently to permit the spirit to run from the holes of the burner 12, whereupon it is ignited. Now commences the gasification in the tube 8, and a heating-flame is produced. The top part 1 of the iron which carries the reservoir being non-conductively separated from the heated bottom part 2, the reservoir is protected against the heat. This protection is increased by the conductingtube 8 being run in a loop through the length of the hollow top part 1, as shown in Fig. l, where it is effectively cooled by a current of fresh air passing in and out through the apertures 15 of this top part as the iron is moved to and fro in being used.

In the modification shown in Figs. 3 and 4 the flames from the burner-tube 12 are deiiected in such manner that they pass only .along the bottom and sides of the iron, leaving the top comparatively cool. The gasifying part of the tube 8 is in this case placed near the side of the iron and is heated by the flames rising between the shield and the side.

At the bottom of the iron a recess 24 may be provided for collecting and there igniting the spirit running from the holes of the burner-tube 12 when the iron is to be started. It is advantageous to place the holes in the bottom part of the burner-tube, as shown in Fig. 4, so that the ames will be directed against the bottom of the iron.

As a matter of course the valve 13 does not only serve for starting the iron, but also for controlling the intensity of the flames, as well as for extinguishing them.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A sad-iron comprising a hollow body or lower part, an open-ended holloviT upper part secured above and ata distance from the lower part or body, a handle secured tothe upper part, a liquid-fuel reservoir between the branches of the handle, a cond acting-tube extending from the reservoir into the lower part or body and having a horizontal portion in said body and a horizontal perforated burnersection in the body communicating with the conducting-tube, substantially as described.

2. A sad-iron comprising a hollow body, or lower part, an open-ended hollow upper part secured above and at a distance from the lower part, a handle secured to the upper part, a liquid-fuel reservoir on the upper part between the branches of the handleha conducting-tube extending through the bottom of the reservoir into the upper part,.doubled back therein, extending through the bottom of said upper part and the space between the upper and lower parts, into the lower part and along the upper part of the chamber of the lower part, a vertical burner-pipe connected to the end of the conducting-tube, and a horizontal perforated branch of the burner-pipe extending along the lower part ot' the chamber of the lower part or body, substantially as described.

3. Asad-iron comprising a hollow body, or lower part, au open-ended hollow upper part secured above and at a distance from the lower part, a handle secured to the upper part, a liquid-fuel reservoir on the upper part, a tube within said reservoir, open at the bottom and extending through the bottom of the reservoir, a non-heat-conducting packing in said openended tube, a conducting-tube inclosed in said packing in the open tube and extending from the top thereof through the reservoir, the upper hollow part, and the lower part or body, and the space between these two latter parts, the portion in the lower part or body extending horizontally to the end thereof, and a burner-tube connected to the end of the conducting-tube in said lower part or body of the iron, substantially as described.

In testimony whereof I affix my signature.
